Now, to be clear, we're not actually sure that these animals are kissing. For all we know, they could just be cleaning each other (according to the San Diego Zoo, pandas clean their fur by licking their paws) or trying to lick really yummy food crumbs off the other's face ... but for now, we choose to believe they're wildly in love.

No matter how uncomfortable the passionate smooches (or whatever they are) made passersby, at least it's not a weird as some of these mating techniques. Read: Feces spraying. Yup.

Cheetah Cubs

Three cheetah cubs, born in November 2004, lean against their mother during a preview showing at the National Zoo in February 2005 in Washington D.C. Today there are just 12,400 cheetahs remaining in the wild, with the biggest population, totaling 2,500 living in Namibia.
